Unless you are a geneticist, chances are you don't have the laboratory equipment or knowledge necessary to extract your own DNA. However, depending on the size of your wallet, $399 may or may not be a lot of money.
My genetics professor introduced this service to me. 23andme is a company that will examine a fraction of your DNA and send you back a comprehensive report detailing, among other things, your genetic predisposition to certain diseases, your ancestry, and comparisons of your genes to a database of people from around the word. Just for FUN I will mention that TIME Magazine named this the 2008 Invention of the Year. whoaaa..................
How does it work? They send you a kit in the mail. You spit in it. You send it back. They extract DNA from the cheek cells found in your saliva and use a "DNA chip" to analyze specific parts of your DNA called SNP's (Single Nucleotide Polymorphisms - regions in your DNA that vary slightly from one person to the next - Believe it or not, your DNA sequence is 99.9% the same as every other person's.)
Still, since the human genome contains billions of base pairs, and since the human genome was only recently mapped, sequencing a person's ENTIRE genome is extremely expensive and time-consuming. Of that 0.1% variation (a few million SNP's), they examine 550,000 SNP's that have been scientifically proven to have some sort of correlation with health and disease risks.
Why would you do this? Most of us are poor teenagers/young adults who can't afford to spend $400 for some DATA and STATISTICS that you can examine. Still, at one point or another in our lives, many of us have heard the hypothetical question of "what would you do if you knew you were going to die soon?" Obviously, this test is not going to tell you that!!! BUT BUT.... the analogy is similar. Many of you would scoff and say "why the fuck would I care? It would be stupid to suddenly change my lifestyle." Others like me may look at things in a different manner - finding out that you have a copy of a gene that has been scientifically linked to a higher risk of Parkinson's Disease or Prostate Cancer might make you curious and lead you to ask your parents about the diseases
their parents suffered from. Many other health factors like heroin addiction, baldness, or heart attacks have been shown to be genetically linked at least in part.
More likely, you are a curious person and think it would be really COOL to have a part of your DNA analyzed, later finding out that your DNA shares a lot of similarities with WESTERN AFRICANS, that you have resistance to malaria, or that you have a 1/4 chance of passing on a gene strongly linked to Diabetes to your kids. Sure, if you were planning on having kids soon you and your mate could technically get an individual test done to find out the likelihood of having a child with diabetes or crohn's disease, but who actually does that unless they are already affected with a disease and KNOW they have a chance of passing it on?
Why would I care?Honestly, I doubt anyone will actually purchase one of these kits (except for nackster or Sarevok maybe lol) but I thought I'd at least share with you guys to let you know that the technology and service exists and is available to the public! DNA sequencing is becoming cheaper and easier every day. Last year this same kit cost $999. Next year it might be $100 or less. My professor is convinced that in the next decade or so, analyzing the DNA of newborn babies will become standard procedure. The impact on the healthcare industry would be ENORMOUS - personalized health care would be just around the block. Doctors would be able to choose a medication or treatment for you that wouldn't necessarily be appropriate for your friend or dad. On the other hand, it would open up doors to genetic discrimination - health providers would want to increase your premiums if they knew you had a higher risk of developing breast cancer.
And before anyone asks - if you send them your sperm instead of your spit, you won't get your money back but you WILL feel rebellious and clever.
